MACHINE FOR POUNCING HATS.

SPECIFICATION forming part of Letters Patent No. 369,520, datedSeptember 6, 1887.

Application filed March 9.1, 1887. Serial No. 231,669. (No model.)

To all whom it may concern.-

Be it known that I, HENR GRIFFIN, of Danbury, in the county of Fairfieldand State of Connecticut, have invented a certain new and usefulImprovement 7 in Machines for Pouncing Hats, of which the following is aspecification.

My improvement relates to machines which are employed for pouncinghat-bodies.

The ordinary pounciug-machine only oper ates upon the crowns of thehat-bodies and not upon the brims.

The object of my improvement is to provide a simple and efi'ective meanswhereby the brims of hat-bodies may also be pounced conveniently andeconomically.

I will describe a hat-pouncing machine embodying my improvement indetail, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a side elevation of ahat-pouncing machine of an ordinary kind, and in connection with whichan apparatus or appliance embodying my improvement may be used. Fig. 2is a side elevation, partly sectional, of an apparatus embodying myimprovement. Fig. 3 is a plan view of Fig. 4 is a side elevation, partlyin section, of an apparatus embodying my improvement in aslightly-modified form. Fig. 5 is a plan view of this last-referred-toapparatus.

Similar letters of reference designate corresponding parts in all thefigures.

I will first describe the hat-pouncing machine which I have representedin Fig. 1, promising, however, that my improvement is not confined inits application to this type of hat-pouncing machine. This machineconsists of a spindle, A, journaled in a frame, B, which may be securelyfastened by screw-bolts or other means to any approved support. Thespindle is provided with pulleys adapted to receive a belt. One of thepulleys is fast on the spindle, and when it receives a belt rotarymotion may be transmitted from the belt to the spindle. The spindle isprovided with a hand -wheel, 0, whereby it may be rotated whendesirable. At one end the spindle is also provided with a chuck, D,serving as a means for securing to the spindle a block adapted toreceive snugly upon it the Ithas been difficult if not impossible withthe appliances hitherto in common use to effect the pouucing of the brimof a hat-body or hat. This difficulty is obviated by myimprove1nent,wl1ich I will now proceed to describe.

My improvement involves the use of a support for sustaining one side ofthe hat-brim and an arm with a pouncing material or a pouncing surfacefor simultaneously acting upon the other side of the hat-brim while thehat is rotated. The part which I have referred to as a support may beprovided with pouncing material or a pouneingsurface as well as the armwhenever it is desirable to effeet the pouncing of both sides of ahat-brim simultaneously.

Usually the apparatus will be so made as to be adapted to operate topounce both sides of the hat-brim at one and the same time, and theapparatus which I have represented embodying my improvement is shown asadapted for such operation.

G G represent two arms or bars shown as united to form a common stock orhand-piece, G Either of these arms or bars may be regarded as thesupport previously referred to, and the other as the arm which I havealso mentioned.

As shown, the two arms or bars G G are intended to be made of wood,preferably a strong, tough, resilient wood, and they are shown asreduced in thickness and in width between the heads or outer ends of thearms or bars and the stock or hand-piece. The

heads or outer ends of the arms or bars are which form the stock orhand-piece are either 'in place by rods 1 I".

fastened directly together or to an intermediate block, and preferablyby means of screws or like devices.

The arms or bars G G are shown as provided at their opposite surfaceswith projections H H", which have pouncingsurfaces. While thesepouncing-surfaces may be made 1n any suitable way, and may even consistof files or other cutting material, yet I deem it desirable to make themof blocks of indiarubbcr or analogous yielding material facedwlthpouncing-paper. I have illustrated them as made in the manner lastdescribed, and they are shown as projecting through slots in the headsor outer end portions of the arms or bars. The india-rubber, c, in eachof the proectlons consists of a strip which is bent over a tongue-piece,b, which may be made of wood and inserted at the ends in grooves b 1),provided in a block of which the tongue-piece forms part. The part ofthe block provided with the grooves, being wider than the tonguepiece,forms shoulders. The tongue-piece,with the strip of rubber around it,projects through a slot in the head or outer end portion of the arm orbar with which it is used. The shoulders of the block of which thetongue-piece forms part extend over the outer surface of the arm or bar,overlapping the end portions of the slot. The blocks may be secured inthe arms or bars in any suitable manner. I have shown them in theexample of my improvement represented by Figs. 2 and 8 as secured Theserods are severally bent at about the middle, so as to form a loop, 2',and at the ends, so as to form hooks i. The hooks engage with eyes i,which are secured to the arm or bar, and the loop engages with a hook,i, also secured to the arm or bar. This hook can be rotated, so as todisengage it from the loop, whereupon the rod previously engaged by thehook can be swung up out of the way, so as to enable the removal of theblock to which the rubber or analogous material is secured. v

The pouncing -surface of the projections H H may be made of short piecesof paper, which will be secured firmly in place between the projectionsand the slots of the arms or bars through which such projections extend.If the projections fit tightly in such slots, the paper will be grippedand held very firmly by reason of the elastic character of theindiarubber or like material forming part of the projections.

The resilience of the arms or bars is such as to cause the projectionsto be pressed toward each other, and this pressure may be varied by thegrasp of the operator. These projections will therefore be held upon thebrim of ahat-body or hat with a firm but yielding force,

' which will be productive of the pressure desired for the pouncingoperation.

I have shown the arms or bars near their outer ends as provided withstops J J",whereby their motion from one another will be limited. Thesestops consist of bars, one of which is provided with a pin and the otherof which has a slot'through which the pin protrudes.

Turning now to the example of my improvement which is shown in Figs. 4and 5, it will be seen that this apparatus is substantially like theother which Ihave already described, except that the blocks of which theprojections H H form parts are connected by hinges K K to the arms orbars, and are therefore free to swing, so that the projections mayrecede or protrude more or less through the slots of the arms or bars.Combined with the hinges K K are springs L L which act upon said hingesin such manner as to force the projections farther through the. slots.Preferably the leaves of the hinges K Kflwhich' are con? nected to theblocks of which the projections form parts, are connected to the ends ofsaid blocks, because when thus made and applied to the blocks theyafford provision for using;

continuous strips of paper for the pouncingsurfaces and drawing the sameover the projections whenever a new surface of paper is needed asa'facing for the projections. The advantage afforded by the-peculiarconstruction and connection of the hinges withthe said blocks is due tothe fact that the leaves of the hinges, when connected to the ends ofthe blocks, will be beyond the slots through which the projections work,and hence will not interfere with the passage of a strip of paperthrough the slots. I have shown in this example of my improvement rollsof pouncingpaper, M 1W, j ournaled in bearings affixed to the arms orbars near their outer ends. The strips of paper from these rolls maypass into the slots over the projections H H then back through the slotsat the other sides of the pro jections and through the leaves of thehinges which are connected to the blocks of which the projectionsform'parts, where they may be either rolled upon other rollers or tornoff. I'

have represented the apparatus as lacking such take-up rollers; hencethe paper may be torn off. As it is useless after having passed theprojections, there is no object in saving it. The paper may be securedagainst movement during the pouncing in the same manner as in theapparatus first describednamely, by being gripped between theprojections and the slots in which such projections fit. If, however,the springs which are oombined with the hinges are so used as to affordto the projections a capacity for yielding additional to that affordedby the yielding of the arms or bars themselves, then the paper will needto be gripped by some other means, because otherwise the yielding of theprojections through the slots would release the paper. Any clamp couldbe used in such case for securing the'paper against movement. If thearms or'bars require greater fiexure than that afforded by making anduniting them in the manner described, they might be hinged together atthe ends forming the stock or handpieee and drawn toward each other bysprings made independent of them.

ICC

An apparatus embodying my improvement may be a hand apparatus1 mean anapparatus unconnected with the pouncing-machine and adapted to be heldin the hand of the operator and supported solelyin that manner-or it mayhave its stock or hand-piece secured to a support forming part ot'orarranged adjacent to the ponncing-machine.

By the use of an apparatus embodying my improvement much labor will besaved in the pouncing of the lorlms of hat-bodies or hats, and this workmay be done much more expeditiously than when done in the ordinarymanner.

That I claim as my invention, and desire to secure by Letters Patent, is

l.
